How to grind dried Reishi mushrooms
October 15, 2013 2:26 PM   Subscribe

I have a huge bag of dried sliced reishi mushrooms. I'm hoping to grind them into a powder so I can make capsules out of them.

I don't want to make a decoction since it seems complicated, time consuming, and I don't want to have to drink it everyday.

Does anyone know how to do this? The texture is actually a lot like bark but maybe less tough. They are sliced, not whole, so I think that makes things a little easier.

I don't have a coffee grinder and would prefer not to but one if I can avoid it, since they're expensive.

Does anyone know if something like this will work?

Here's a coffee grinder that's the same price as your weed grinder. It'll get the job done a whole lot faster.

The item you linked to is $9; the third-best-reviewed coffee grinder on Amazon is only $12. Just get a coffee grinder, it will pulverize anything to an even powder with no effort on your part.

Regular ol' food processor will do it.

Just blitz them (heh) until they're powder.

The harder/drier they are the better. You can dry them out further by placing them in a gas oven overnight with nothing but the pilot light if you live in warm/dry climes, an oven hovering about 150 degrees F if in colder or wet climes.

That grinder is small. It's only 2" in diameter and will hold maybe a tablespoon of ground material at most. If it's like the others I've seen, the teeth are pretty strong and will grind through most anything.

I use a Krups blade mill for all such grinding tasks, it's only $20 for the basic one at amazon. I'd go for that.

I would not process a huge bag of mushrooms in a small grinder, but I have both a food processor and a grinder to choose from...

I imagine it will take a good few minutes in the food processor to turn each batch into powder, fwiw.

I wouldn't bother making capsules, it's such a pain, even with a machine!

I would mix the powder with hot water to make tea or sludge, and just slurp it down real quick.

Response by poster: Thanks everybody for your answers!

I think I will try my mini food processor and see if it works, though I feel like it won't make a powder out of them. If that doesn't work I guess I'll go with a cheap coffee grinder after all. And also dry them out further. jbenben, I agree that making capsules is a pain, but I'm used to it. I do it with a lot of stuff and since it's cheaper I can take more supplements than I could if I bought ready made capsules. And I can buy organic too. Organic capsules are still not very common.

If your food processor can't handle this job, find a replacement food processor.

+1 drier-the-better -- if you can take it from 'bark' to 'brittle' you should have a much easier time.

If you have an enormous dept-store-style thrift store near you you can get a basic coffee grinder for very cheap. (If it's already been used for coffee, try processing rice until it looks clean and then swabbing it out with alcohol.)

Ikea has a cheapish mortar and pestle if you want another pain to get used to.

If they are really rubbery and a pain to grind, they might blend well in a blender with some sort of liquid thrown in, like gently warmed coconut oil. You could take the resulting mushroom-oil sludge and form it into swallowable shapes. One way to do this is with a disposable plastic pipette (cheap on eBay) and drinking straws; tape one end of the straws shut, pipe the slurry into the straws, let it harden, dip the straw under hot water for a moment and extrude the contents, and slice that and store it in the fridge.
